Mineral surfaces and bioavailability of heavy metals : a molecular-scale perspective
TL;DR: This work has used extremely intense x-rays from synchrotron sources and a structure-sensitive method known as x-ray absorption fine structure (XAFS) spectroscopy to determine the molecular-level speciation of heavy metal and metalloid contaminants in various environmental settings.

Quantitative speciation of lead in selected mine tailings from Leadville, CO
TL;DR: In this article, the authors characterized Pb speciation in selected tailings from the Leadville, CO, area using a variety of analytical techniques, including X-ray absorption fine structure (XAFS) spectroscopy.

Regular ArticleInorganic Ligand Effects on Pb(II) Sorption to Goethite (α-FeOOH): I. Carbonate
TL;DR: Characterizing the structures of Pb(II) sorption complexes formed on goethite (alpha-FeOOH) in the presence of carbonate using in situ Pb L(III)-EXAFS and ATR-FTIR spectroscopies suggests the existence of ternary surface complexes in which carbonate groups bond to Pb as monodentate ligands.
